tree.

73614abf37 [CMake] Implement generation of Z3Config.cmake and Z3Target.cmake 
file for the build and install tree.

These files allow users of CMake to use Z3 via a CMake config package.
Clients can do `find_package(Z3 CONFIG)` to get use the package from
their projects.

When generating the files for the install tree we try to generate
the files so that they are relocatable so that it shouldn't matter
if the installed files aren't in the CMAKE_INSTALL_PREFIX when
a user consumes them. As long as the relative locations of the files
aren't changed things should still work.

A new CMake cache variable `CMAKE_INSTALL_Z3_CMAKE_PACKAGE_DIR` has been
added so that the install location of the Z3 CMake package files can be
controlled.

This addresses #915 .

e2933350b2 Merge pull request #937 from delcypher/cmake_git_version 
[CMake] Support including Git hash and description into the build.
 2017-03-12 23:36:21 +01:00
Dan Liew
2cb4223979 [CMake] Support including Git hash and description into the build. 
CMake will automatically pick up changes in git's HEAD so that
the necessary code is rebuilt when the build system is invoked.

Two new options `INCLUDE_GIT_HASH` and `INCLUDE_GIT_DESCRIBE` have been
added that enable/disable including the git hash and the output of `git
describe` respectively. By default if the source tree is a git
repository both options are on, otherwise they are false by default.

To support the `Z3GITHASH` macro a different implementation is used from
the old build system. In that build system the define is passed on the
command line. This would not work well for CMake because CMake
conservatively (and correctly) rebuilds *everything* if the flags given
to the compiler change. This would result in the entire project being
rebuilt everytime git's `HEAD` changed.  Instead in this implementation
a CMake specific version of `version.h.in` (named `version.h.cmake.in`)
is added that uses the `#cmakedefine` feature of CMake's
`configure_file()` command to define `Z3GITHASH` if it is available and
not define it otherwise. This way only object files that depend on
`version.h` get re-built rather than the whole project.

It is unfortunate that the build systems now have different `version.h`
file templates. However they are very simple and I don't want to
modify how templates are handled in the python/Makefile build system.
