Hmm, quickly trying librepcb-1.2.0, the build quickly dies here,
CMake Error at /@unixroot/usr/lib/cmake/Qt5/Qt5Config.cmake:28 (find_package):
Could not find a package configuration file provided by "Qt5OpenGL" with
any of the following names:
Qt5OpenGLConfig.cmake
qt5opengl-config.cmake
Add the installation prefix of "Qt5OpenGL" to CMAKE_PREFIX_PATH or set
"Qt5OpenGL_DIR" to a directory containing one of the above files. If
"Qt5OpenGL" provides a separate development package or SDK, be sure it has
been installed.
Call Stack (most recent call first):

-- Configuring incomplete, errors occurred!
The readme does claim that OpenGL is optional along with another library. Have to look closer after work.
