#  WARNING: This script uses file(GLOB ...) function. YOU MUST
#  recompile this CMake script once any new file is added.
#
# Usage:
#   a) DEBUG build for testing.
#     cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_INSTALL_PREFIX=/usr

# Generating source tarballs:
#   make dist or make package_source
#
# Generating binary tarballs:
#   make package
#
# Other information:
#   - supports Windows, Linux, OS/2 (eComStation),
#   - Qt 5.6 and higher is required,
#   - resource compiler (windres.exe) is needed on MinGW,
