When CxxTest is installed in /usr/bin and friends according to FHS and proper packaging our FindCxxTest.cmake script will fail:

0#11:49:29#math@voltaire# FiberClusteringToolbox/build/release >make
[  4%] [  9%] [ 14%] Copying resources for ClusteringToolbox to build directory

make[2]: *** [unittest_WGaussProcess.cc] Error 127
make[1]: *** [CMakeFiles/unittest_WGaussProcess.dir/all] Error 2
make: *** [all] Error 2

As the script will not search in those paths:

find_path(CXXTEST_INCLUDE_DIR cxxtest/TestSuite.h)
find_program(CXXTEST_PERL_TESTGEN_EXECUTABLE cxxtestgen.pl
PATHS ${CXXTEST_INCLUDE_DIR})
find_program(CXXTEST_PYTHON_TESTGEN_EXECUTABLE cxxtestgen.py
PATHS ${CXXTEST_INCLUDE_DIR})
include(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(CxxTest DEFAULT_MSG CXXTEST_INCLUDE_DIR)
set(CXXTEST_INCLUDE_DIRS ${CXXTEST_INCLUDE_DIR})

However, there exists a new FindCxxTest.cmake script within the cmake-data debian package. Using this will succeed when outside of our build system. That means, just copying over to our code base will result in the following cmake error:

CMake Error at /home/math/repos/ow-modules/FiberClusteringToolbox/tools/cmake/FindCxxTest.cmake:170 (include):
include could not find load file:
/home/math/repos/ow-modules/FiberClusteringToolbox/tools/cmake/FindPackageHandleStandardArgs.cmake
Call Stack (most recent call first):
/home/math/repos/ow-modules/FiberClusteringToolbox/tools/cmake/OpenWalnut.cmake:338 (FIND_PACKAGE)
CMakeLists.txt:52 (INCLUDE)

So either we adapt the find script and replace the old one, or remove it. I suggest for adapting as removing it will leave systems with no such new cmake-data broken to unit test generation.
