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.
