Wonderful project "protobuf" ("protobuf" with a small letter "f") starting with
version 3.0 (which is around the corner - now beta 2), will be built with CMake
on Windows, and will contain CONFIG scripts with a description of the exported
package and an imported goal.
That's the name of the project:
https://github.com/google/protobuf/blob/master/cmake/CMakeLists.txt#L5
All targets will be installed in the standard paths, which optionally can be
configured to your needs (use the GNUInstallDirs module):
https://github.com/google/protobuf/blob/master/cmake/install.cmake#L10
There is also the option to configure Postfix in a debug configuration
(protobuf_DEBUG_POSTFIX - default "d"):
https://github.com/google/protobuf/blob/master/cmake/CMakeLists.txt#L26
So for protobuf >= 3.0 on Windows you can use
design:
find_package(protobuf CONFIG)
These new features were created with my participation. I tried to create a
configuration compatible with the all of us known module. Here is a template
script compatibility for the module:
https://github.com/google/protobuf/blob/master/cmake/protobuf-module.cmake.in
Unfortunately, for platforms other than Windows, use CMake to build protobuf
not officially planned, but carried out private studies confirm the fact that
cmake/CMakeLists workable on other platforms.
Thus the project "protobuf" already cmake/CMakeLists.txt and is open to
modifications and development for the benefit of the CMake community.
While we will continue to work as follows:
find_package(Protobuf [MODULE])
But over time, I hope to do just so:
find_package(protobuf CONFIG)
All suggestions and comments as always are welcome.
And for publicity :-)
You can try pre-built protobuf me 3.0 for Windows (MSVC2013) from Dad's Project
