c++, cxxtest, cmake

Been messing around lately with CMake and how to intregrate additional testing frameworks such as CxxTest. So far everything has been very simple to configure and get setup so I thought I'd post my findings here.

1) Fedora provides both cmake and cxxtest so install these first.
2) CMake provides a convenience macro called FindCxxTest.cmake
3) In your CMakeLists.txt append the following:

# cxxtest
find_package(CxxTest)
if(CXXTEST_FOUND)
set(CXXTEST_USE_PYTHON TRUE)
include_directories(${CXXTEST_INCLUDE_DIR})
enable_testing()
CXXTEST_ADD_TEST(unittest_sos check_sos.cpp ${SOS_TEST_PATH}/check_sos.h)
target_link_libraries(unittest_sos sos)
endif()

The only custom variable here is SOS_TEST_PATH which basically points to $HOME/sos/tests/check_sos.h. See the 'set' function in the cmake documentation.

This is really all you need to do here. One note is to set the CXXTEST_USE_PYTHON to TRUE b/c cmake provided in Fedora doesn't contain the perl version of the test generator.

I'm not going to post how I setup the testcases b/c right now they are very simple, however, if you would like to use my project as an example for implementing cmake into your code have a look at: libsos

If anyone has any good information on using cmake with python build scripts I'd love to see those.

For RPM Builders the spec file was very simple. I used the syntax within the kde builds:

%build
mkdir -p %{_target_platform}
pushd %{_target_platform}
cmake ..
popd

make %{?_smp_mflags} -C %{_target_platform}

%install
rm -rf $RPM_BUILD_ROOT
make -C %{_target_platform} install DESTDIR=$RPM_BUILD_ROOT
%clean
rm -rf $RPM_BUILD_ROOT


%post -p /sbin/ldconfig

%postun -p /sbin/ldconfig


%files
%defattr(-,root,root,-)
%doc
%{_libdir}/%{name}.so.*

%files devel
%defattr(-,root,root,-)
%doc
%{_includedir}/%{name}
%{_libdir}/%{name}.so*
%{_libdir}/pkgconfig/%{name}.pc

Hope this little bit will help others who are interested in cmake.
