#
#  This is RSS Guard compilation script for CMake.
#
# Usage:
#   a) DEBUG build for testing.
#     cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_INSTALL_PREFIX=/usr -DUSE_QT_5=ON
#
#   b) RELEASE build for production use.
#     cmake -DCMAKE_BUILD_TYPE=release -DCMAKE_INSTALL_PREFIX=/usr -DUSE_QT_5=ON
#
# Arguments:
#   -DCMAKE_INSTALL_PREFIX=/usr
#     Installation path, replace with something like "C:\rssguard" on Windows.
#
#   -DUSE_QT_5=OFF
#     Specifies which major Qt version to use. Qt 4 and Qt 5 are supported.
#     If "OFF" is passed as an argument, then Qt 4 is used. Default is "OFF".
#
#   -DBUNDLE_ICON_THEMES=ON
#     If "ON", then custom icons theme(s) will be bundled with application
#     installation. If "OFF", then no icon theme(s) will be available for
#     the application and application will run in iconless mode.
#     Default and recommended value is "ON".
#
#   -DENABLE_OS2_RC=OFF
#     If "ON" then icon is compiled into executable file on OS/2. Defaults to "OFF".
#
# Refreshing translation sources:
#   make lupdate
#
# Generating source tarballs:
#   make dist or make package_source
#
# Generating binary tarballs:
#   make package
#
# Other information:
#   - supports Windows, Linux, OS/2 (eComStation),
#   - Qt 4.7.3 and higher is required,
#   - resource compiler (windres.exe) is needed on MinGW,
#   - resource compiler (rc.exe) is recommended on OS/2.
#
# Authors and contributors:
#   - Martin Rotter (project leader),
#   - Elbert Pol (huge OS/2-related contributions)
