[CMake] issue with CPack: RPM package was not generated!

[Miroslav Kubiczek]

yes, there are install commands, one of CMakeLists.txt content:

install(DIRECTORY ${PROJECT_SOURCE_DIR}/api/rest DESTINATION include)
install(TARGETS Rest DESTINATION lib)

I can see these files after running the 'make package':
$ find ./_CPack_Packages/Linux/
./_CPack_Packages/Linux/
./_CPack_Packages/Linux/RPM
./_CPack_Packages/Linux/RPM/SOURCES
./_CPack_Packages/Linux/RPM/rpmbuildXXX-common-cpp-libs.err
./_CPack_Packages/Linux/RPM/tmp
./_CPack_Packages/Linux/RPM/rpmbuilXXX-common-cpp-libs.out
./_CPack_Packages/Linux/RPM/BUILDROOT
./_CPack_Packages/Linux/RPM/SRPMS
./_CPack_Packages/Linux/RPM/BUILD
./_CPack_Packages/Linux/RPM/SPECS
./_CPack_Packages/Linux/RPM/SPECS/XXX-common-cpp-libs.spec
./_CPack_Packages/Linux/RPM/RPMS
./_CPack_Packages/Linux/RPM/XXX-common-cpp-libs-7.0.0-1.x86_64.rpm

I'm generating the spec file from a template by:
configure_file("${CMAKE_CURRENT_SOURCE_DIR}/rpm/xxx-common-cpp-libs.spec.in"
"${CMAKE_CURRENT_BINARY_DIR}/xxx-common-cpp-libs.spec" @ONLY IMMEDIATE)

The genereated spec file looks like this:

Buildroot:
/data/git/common-cpp-libs/build/_CPack_Packages/Linux/RPM/xxx-common-cpp-libs-7.0.0-1.x86_64
Summary:        xxx common cpp libs

%define _unpackaged_files_terminate_build 0
%define _topdir /data/git/common-cpp-libs/build/_CPack_Packages/Linux/RPM

# This is a shortcutted spec file generated by CMake RPM generator

then
  rm -Rf $RPM_BUILD_ROOT
fi
mv "/data/git/common-cpp-libs/build/_CPack_Packages/Linux/RPM/tmpBBroot"
