 | # 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 occurrence 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. | 
 | # |
