Problem loading test projects with QT Community

CMake Error at CMakeLists.txt:42 (gdx_setup_target):
Unknown CMake command "gdx_setup_target".

CMake Warning at CMakeLists.txt:8 (find_package):
By not providing "FindGdxCpp.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "GdxCpp", but
CMake did not find one.

Could not find a package configuration file provided by "GdxCpp" with any
of the following names:

GdxCppConfig.cmake
gdxcpp-config.cmake

Add the installation prefix of "GdxCpp" to CMAKE_PREFIX_PATH or set
"GdxCpp_DIR" to a directory containing one of the above files. If "GdxCpp"
provides a separate development package or SDK, be sure it has been
installed.

QProcessPrivate::execChild() failed to chdir to /home/victor/build/gdxcpp-tests

Is there another way of loading the projects instead of using QT?
