¶ ## Collect Source Files |
¶ NOTE: A `GLOB` operation is quick, but may not be appropriate. It may be better to maintain an explicit list of source files. Particularly, adding a new file to an explicit list will cause CMake to automatically reconfigure the next time `make` is invoked. When `GLOB` is used, the developer will have to remember to re-run `cmake` if a source file is added. |
    FILE(GLOB TEXWORKS_SRCS       "*.cpp" "*.c")
    FILE(GLOB TEXWORKS_MOC_HDRS   "*.h")

    FILE(GLOB TEXWORKS_RCS        "${TeXworks_SOURCE_DIR}/res/*.qrc")
    FILE(GLOB TEXWORKS_TRANS      "${TeXworks_SOURCE_DIR}/trans/*.ts")
¶ These source files along with the `.moc` files generated from some headers form the TeXworks scripting API. We export them to variables in the `PARENT_SCOPE` (top level CMake file) so that they will be available to the build processes of the scripting language plugins. |
