define HELP_TEXT

LuxCoreRender Convenience Targets
   Provided for building (multiple targets can be used at once).

   * debug:         Build a debug binary.
   * ccache:        Use ccache for faster rebuilds.

Other Convenience Targets
   Provided for other building operations.

   * deps:          Build library dependencies (intended only for platform maintainers).

Environment Variables

   * BUILD_CMAKE_ARGS:      Arguments passed to CMake.
   * BUILD_DIR:             Override default build path.
   * BUILD_TYPE:            Debug or Release
   * BUILD_STATIC:          Build dep libs static
   * NPROCS:                Number of processes to use building (auto-detect when omitted).

Information

   * help:              This help message.
