Disable the CMake_INSTALL_DEPENDENCIES option by default and turn it on
explicitly in our packaging scripts. This simplifies packaging in
distributions that provide the dependencies for us without having to
install them. We only need 3rd-party runtime dependencies to be
installed for packaging with redistributable binaries.
Download http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt and place
it as Licenses/LGPLv2.1.txt in our source tree. When building cmake-gui,
use option CMake_GUI_DISTRIBUTE_WITH_Qt_LGPL to enable notification
in the "About" dialog of how the distribution of Qt is licensed.
Install the license file as ${CMAKE_ROOT}/Licenses/LGPLv2.1.txt so that
the dialog can display a path to it.
Our Linux release machine 'magrathea' has a very old Linux to help build
portable binaries. It is so old that <elf.h> does not define the
DT_RUNPATH constant. Define the correct value in the build flags to
activate handling of ELF RUNPATH entries in the binary release.
Set GIT_COMMAND to "git" -- each machine involved in building
the CMake release binaries has the right "git" in the PATH.
Separate the release scripts into two batches so we can build
multiple releases on the same machine, in serial, if necessary.
We currnetly do this with the Windows and Cygwin release
binaries on dash2win64.
Sort the files to be uploaded, so that sorting them by modification
time (file copy / upload time) is equivalent to sorting them
alphabetically.
