I am using Buck for my own C++ project, but I depend on a third-party library that is built using CMake. The CMake file is complex, so I do not think it is practical to recreate their CMake file in Buck. Instead, I would like to call CMake from Buck.
What is the best way to call CMake from Buck?
How should I structure my project to minimise headaches?
My suggestion is using genrule and prebuilt_cxx_library.
This is my Buck study project using Google Test: https://github.com/ar90n/lab/tree/master/sandbox/buck-study/gtest
This project contains two Buck files. The one (./gtest/BUCK) is for fetching and building Google Test. The another (./BUCK) is for building and running test programs.
If you want to build and run this project, please execute the following commands,
$ buck fetch //gtest:googletest-src
$ buck build :sample1
$ buck run :sample1
