Subject: [PATCH] Introduced cmake module registerTests:
usage:
register_tests(SOURCES
${list_of_source_files}
"test_src.cc"
${concatenated_string_of_source_files}
NAMESPACE
"test_namespace"
DEPENDS
${list_of_targets}
INCLUDES
${list_of_include_directories}
COMPILE_OPTIONS
${list_of_compile_options})
Function registers tests defined as a list of souce files. Test defined
by file source_name.cc in the SOURCES list is registered under the name
test_namespace.source_name
Provided list of dependent targets and include directories are used for
test executables as PRIVATE dependencies during compilation.
Function implicitly adds a dependency on the boost unit test framework
to each generated test executable.
