An new environment variable 'CMAKE_INSTALL_MODE' is introduced, which can be used to ask CMake to create symbolic links instead of copying files during a file(INSTALL ...). The operation is at the file level only, directory trees are still created using actual directories, not links. Signed-off-by: Felix Lelchuk <felix.lelchuk@gmx.de>

This is an example superbuild project to demonstrate the use of the
|
|
CMAKE_INSTALL_MODE environment variable on.
|
|
|
|
The project hierarchy is like (B = Builds / D = Link Dependency):

The superbuild system is built on top of ExternalProject_Add().
|
|
|
|
NOTE that the subprojects will configure, build and install
|
|
during the build phase ('make') of the top-level project.
|
|
There is no install target in the top-level project!
|
|
The CMAKE_INSTALL_PREFIX is therefore populated during the build
|
|
phase already.
