Subject: [PATCH] Improve support for distribution-specific builds
- Rename the DRI_DRIVER_PATH and SERVER_MISC_CONFIG_PATH CMake variables
to XORG_DRI_DRIVER_PATH and XORG_REGISTRY_PATH, respectively.
- Introduce a new CMake variable (XORG_FONT_PATH) that allows the X.org
font path to be set statically for a particular build.
- Remove the unused RGB_DB macro definition. (That macro hasn't been
used since TurboVNC 1.2.x.)
- Introduce a new CMake variable (TVNC_STATIC_XORG_PATHS) that forces
Xvnc and vncserver to honor the paths set using the
XKB_BASE_DIRECTORY, XKB_BIN_DIRECTORY, XORG_DRI_DRIVER_PATH,
XORG_FONT_PATH, and XORG_REGISTRY_PATH CMake variables rather than
trying to determine the appropriate values of those paths at run time.
If enabled, this option disables the TurboVNC-specific -dridir,
-registrydir, and -xkbcompdir Xvnc command-line arguments.

+### Distribution-Specific Build
+
+By default, the build system builds TurboVNC binaries that can run on multiple
+O/S distributions. This involves building some of the X.org dependencies,
+which are included in the TurboVNC source tree, and statically linking TurboVNC
+with those and other dependencies. Distribution-specific dynamically-linked
+TurboVNC binaries can instead be built by changing the values of the following
+CMake variables:
+
+- `TJPEG_INCLUDE_DIR`
+- `TJPEG_LIBRARY`
+- `TVNC_DLOPENSSL`
+- `TVNC_STATIC_XORG_PATHS`
+- `TVNC_SYSTEMLIBS`
+- `TVNC_SYSTEMX11`
+- `XKB_BASE_DIRECTORY`
+- `XKB_BIN_DIRECTORY`
+- `XORG_DRI_DRIVER_PATH`
+- `XORG_FONT_PATH`
+- `XORG_REGISTRY_PATH`
+
+Use `ccmake` or `cmake-gui`, as described below, to view documentation for
+those variables.
