If solid is missing, configuration with cmake will fail.
[snip] CMake Error at CMakeLists.txt:18 (find_package): By not providing "FindKF5Solid.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "KF5Solid", but CMake did not find one. Could not find a package configuration file provided by "KF5Solid" with any of the following names: KF5SolidConfig.cmake kf5solid-config.cmake Add the installation prefix of "KF5Solid" to CMAKE_PREFIX_PATH or set "KF5Solid_DIR" to a directory containing one of the above files. If "KF5Solid" provides a separate development package or SDK, be sure it has been installed. [/snip]
