# Macro to add a test
#
# the unique mandatory parameter testname must correspond to a file
# <testname>.cpp which follows this pattern:
#
# #include "main.h"
# void test_<testname>() { ... }
#
# Depending on the contents of that file, this macro can have 2 behaviors,
# see below.
#
# The optional 2nd parameter is libraries to link to.
#
# A. Default behavior
#
# this macro adds an executable <testname> as well as a ctest test
# named <testname> too.
#
# On platforms with bash simply run:
# "ctest -V" or "ctest -V -R <testname>"
# On other platform use ctest as usual
#
# B. Multi-part behavior
#
# If the source file matches the regexp
# CALL_SUBTEST_[0-9]+|EIGEN_TEST_PART_[0-9]+
# then it is interpreted as a multi-part test. The behavior then depends on the
# CMake option EIGEN_SPLIT_LARGE_TESTS, which is ON by default.
#
# If EIGEN_SPLIT_LARGE_TESTS is OFF, the behavior is the same as in A (the multi-part
# aspect is ignored).
#
# If EIGEN_SPLIT_LARGE_TESTS is ON, the test is split into multiple executables
# test_<testname>_<N>
# where N runs from 1 to the greatest occurence found in the source file. Each of these
# executables is built passing -DEIGEN_TEST_PART_N. This allows to split large tests
# into smaller executables.
#
# Moreover, targets <testname> are still generated, they
# have the effect of building all the parts of the test.
#
# Again, ctest -R allows to run all matching tests.
