Trying to package lmms 1.2.0 RC5 for Rosa Linux Fresh R10 (a Mandriva derivative) on x86_64.
Cmake stops with the error message:
CMake Error at src/3rdparty/CMakeLists.txt:6 (add_subdirectory):
The source directory /tmp/abf/rpmbuild/BUILD/lmms-1.2.0-rc5/src/3rdparty/qt5-x11embed
does not contain a CMakeLists.txt file.
Attached the full log
BuildFailure.txt
Indeed the directory src/3rdparty/qt5-x11embed is empty in the RC5 tarball, while it is absent in the RC4 one (and using it produces a successful build).
So I guess you will need to regenerate the source tarball for 1.2.0 RC5...
