Osrm-backend: Can't compile on Debian Wheezy 7.10

[rfreytag1]

Hello,
I tried to compile OSRM on a Debian Wheezy 7.10 machine but unfortunately failed.
The issue seems to be that CMake is too old, but it's not really mentioned on the Wiki-Page about building that there might be issues on Wheezy.
Anyway, this is what cmake prints:

CMake Error at src/benchmarks/CMakeLists.txt:9 (target_include_directories):
  Unknown CMake command "target_include_directories".

You are correct, it seems like target_include_directories is not in CMake 2.8.9:
https://cmake.org/cmake/help/v2.8.9/cmake.html

but only in 3.0+:
https://cmake.org/cmake/help/v3.0/command/target_include_directories.html

Quick workaround for you:

• either try changing target_include_directories to include_directories and remove the first argument (the target)
• or download a 3.x CMake (either the binary or grab the sources and compile via ./bootstrap && make && make install in order to install it to /usr/local/)

"Fixed" in https://github.com/Project-OSRM/osrm-backend/commit/87f00d2c4c2403dd98d81f7206d35ce20d26c943 :) we rely on target_include_directories since it's an essential feature that allows us to not clobber the global namespace with includes we only require in specific targets.

I will add a note to the Wiki.
