+# 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.
