The CMake `try_compile` command is especially slow for
the Xcode generator. With this patch applied it first tests
for the currently used (and Open Group specified) send/recv
signature. In case this fails testing falls-back to the
permutations.

When using clang-cl on windows -fvisibility=hidden is not an known
argument. Instead it behaves exactly like MSVC in this case. So let's
make sure we take that path.
In CMake clang-cl sets both CMAKE_C_COMPILER_ID=clang and MSVC get's
defined since clang-cl is basically a MSVC emulator. So guarding like we
do in this patch seems logical.

Add three new CMake Find modules (using the curl license, but I grant
others the right to apply the CMake BSD license instead).
This CMake config is simpler than the autotools one because it assumes
ngtcp2 and nghttp3 to be used together. Another difference is that this
CMake config checks whether QUIC is actually supported by the TLS
library (patched OpenSSL or boringssl) since this can be a common
configuration mistake that could result in build errors later.
Unlike autotools, CMake does not warn you that the features are
experimental. The user is supposed to already know that and read the
documentation. It requires a very special build environment anyway.
Tested with ngtcp2+OpenSSL+nghttp3 and quiche+boringssl, both built from
current git master. Use `LD_DEBUG=files src/curl |& grep need` to figure
out which features (libldap-2.4, libssh2) to disable due to conflicts
with boringssl.
Closes#5359
We use `check_c_source_compiles` to check possible send/recv signatures
by reproducing the forward declarations from system headers. On Windows
the `winsock2.h` header adds dll linkage settings to its forward
declaration. If ours does not match the compiler warns:
warning C4273: 'recv': inconsistent dll linkage
Add `WINSOCK_API_LINKAGE` to our test signatures when it is defined so
that our linkage is consistent with that from `winsock2.h`.

With CMAKE_TRY_COMPILE_TARGET_TYPE set to STATIC_LIBRARY, the try_compile()
(which is used by check_c_source_compiles()) will build static library
instead of executable. This avoids linking additional libraries in and thus
speeds up those checks a little.
This commit also avoids #3743 (GSSAPI build errors) on itself with cmake
3.6 or above. That issue was fixed separately for all versions.
Ref: #3744
Use 'GNUInstallDirs' standard module to set destinations of installed
files.
Use uppercase "CURL" names instead of lowercase "curl" to match standard
'FindCURL.cmake' CMake module:
* https://cmake.org/cmake/help/latest/module/FindCURL.html
Meaning:
* Install 'CURLConfig.cmake' instead of 'curl-config.cmake'
* User should call 'find_package(CURL)' instead of 'find_package(curl)'
Use 'configure_package_config_file' function to generate
'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template
file smaller and handle components better. E.g. current configuration
report no error if user specified unknown components (note: new
configuration expects no components, report error if user will try to
specify any).

Fix the check code to pass 5 arguments instead of 6. This typo was
introduced by commit aebfd4cfbf (cmake: fix gethostby{addr,name}_r in
CurlTests, 2014-10-31).
Set CMAKE_REQUIRED_DEFINITIONS to include definitions needed to get
the winsock2 API from windows.h. Simplify the order of checks to
avoid extra conditions.
Use check_include_file instead of check_include_file_concat to look
for OpenSSL headers. They do not need to participate in a sequence
of dependent system headers. Also they may cause winsock.h to be
included before ws2tcpip.h, causing the latter to not be detected
in the sequence.

Remove use of an old hack that takes advantage of the auto-dereference
behavior of the if() command to detect if a variable is defined. The
hack has the form:
if("${VAR} MATCHES "^${VAR}$")
where "${VAR}" is a macro argument reference. Use if(DEFINED) instead.
This also avoids warnings for CMake Policy CMP0054 in CMake 3.1.

The check_include_file_concat macro is intended to be called multiple

For example, many POSIX APIs document including sys/types.h before some

There were several -Wunused warnings and one duplicate macro definition.
The EXTRA_DEFINES variable of the CurlCheckCSources macro was being
abused ("__unused1\n#undef inline\n#define __unused2", seriously?) to
insert extra C code. Avoid this broken abstraction and use cmake's
check_c_source_compiles directly (works fine with CMake 2.8, maybe
even cmake 2.6).
After cleaning up all related variables (EXTRA_DEFINES,
HEADER_INCLUDES, auxiliary headers_hack), also remove a duplicate
add_headers_include macro and remove duplicate header additions before
the struct timeval check.
Oh, and now the code is converted to use CheckCSourceRuns and
CheckCSourceCompiles, the two curl-specific helpers can be removed.
Unfortunately, the cmake output is now slightly more verbose. Before:
Performing Test int send(int, const void *, size_t, int) (curl_cv_func_send_test)
Performing Test int send(int, const void *, size_t, int) (curl_cv_func_send_test) - Failed
Since check_c_source_compiles prints the varname, now you see:
Performing Test curl_cv_func_send_test
Performing Test curl_cv_func_send_test - Failed
Tested: int send(int, const void *, size_t, int)

This patch cleans up the automatically-generated (?) code and fixes one
case that will always fail due to syntax error.
HAVE_GETHOSTBYADDR_R_5_REENTRANT always failed because of a trailing
character ("int length;q"). Several parameter type and unused variable
warnings popped up. This causes a detection failure with -Werror.
Observe that the REENTRANT cases are exactly the same as their
non-REENTRANT cases except for a `_REENTRANT` macro definition.
Merge all these pieces and build one big main function with different
cases, but reusing variables where logical.
For the cases where the parameters where NULL, I looked at
lib/hostip4.c to get an idea of the parameters types.

Because we prepended libraries to list, CMake had troubles resolving
link directory order as it detected some cycles. Appending to list ensures
that dependencies will preceed dependees.
One header at a time is the right way. Apart from that the output on

CMake 2.6 is already a bit old. Many bugs have been fixed since
its release. We use 2.8 in our company and we have no intention
of polluting our environment with old software, so 2.6 would
not be tested. This shouldn't be a problem since all one need
to build CMake from source is C and C++ compiler.
All C and H files now (should) feature the proper project curl source
code header, which includes basic info, a copyright statement and some
basic disclaimers.
The CheckTypeSize module that comes with CMake 2.6.2 and above does
everything we need and also supports cross-compiling. Avoid duplicating
an older version of it here. This also fixes a cross-compiling error
because the old line
include ("${CMAKE_MODULE_PATH}/CheckTypeSize.cmake")
failed because CMAKE_MODULE_PATH is a search path and not a directory.
