     87 # Macro to add a test
     88 #
     89 # the unique mandatory parameter testname must correspond to a file
     90 # <testname>.cpp which follows this pattern:
     91 #
     92 # #include "main.h"
     93 # void test_<testname>() { ... }
     94 #
     95 # Depending on the contents of that file, this macro can have 2 behaviors,
     96 # see below.
     97 #
     98 # The optional 2nd parameter is libraries to link to.
     99 #
    100 # A. Default behavior
    101 #
    102 # this macro adds an executable <testname> as well as a ctest test
    103 # named <testname> too.
    104 #
    105 # On platforms with bash simply run:
    106 #   "ctest -V" or "ctest -V -R <testname>"
    107 # On other platform use ctest as usual
    108 #
    109 # B. Multi-part behavior
    110 #
    111 # If the source file matches the regexp
    112 #    CALL_SUBTEST_[0-9]+|EIGEN_TEST_PART_[0-9]+
    113 # then it is interpreted as a multi-part test. The behavior then depends on the
    114 # CMake option EIGEN_SPLIT_LARGE_TESTS, which is ON by default.
    115 #
    116 # If EIGEN_SPLIT_LARGE_TESTS is OFF, the behavior is the same as in A (the multi-part
    117 # aspect is ignored).
    118 #
    119 # If EIGEN_SPLIT_LARGE_TESTS is ON, the test is split into multiple executables
    120 #   test_<testname>_<N>
    121 # where N runs from 1 to the greatest occurence found in the source file. Each of these
    122 # executables is built passing -DEIGEN_TEST_PART_N. This allows to split large tests
    123 # into smaller executables.
    124 #
    125 # Moreover, targets <testname> are still generated, they
    126 # have the effect of building all the parts of the test.
    127 #
    128 # Again, ctest -R allows to run all matching tests.
