General / Re: CMake in SFML 2.5

« on: June 08, 2018, 11:49:04 am »

So far I have tried using add_subdirectory() to generate the SFMLCmake.config file, and then using find_package(). (This looks very hacky to me...)

add_subdirectory(${SRCDIR}/lib/SFML-2.5.0)
set(SFML_DIR ${BINDIR}/lib/SFML-2.5.0)
find_package (SFML 2.5 REQUIRED window graphics system)
 

Cmake runs fine and SFML builds, but i still get linker errors:

<me> in ~/Desktop/tutorial-sfmlcmake/build
$ make
BINDIR/Users/<me>/Desktop/tutorial-sfmlcmake/build
SRCDIR/Users/<me>/Desktop/tutorial-sfmlcmake

When I turn off static build, building SFML works, but it is still a two step process. Like OP I want to be able to build SFML as part of my project in a single make call

Reiterating what OP said:
 "...my current workflow is to call CMake twice - once for SFML, and once for my project. I would like to be able to set up my project such that SFML appears as part of the resultant solution/etc."

I think I have a similar issue. I am trying to build SFML 2.5 statically on macOs in a single step,
together with the rest of my project.

This is how i want it to work.

git clone <myrepo>
mkdir build
cd build
cmake ..
make
./tutorialsfml
 

Here is the current output from my cmake ..

$ cmake ..
BINDIR /Users/<me>/Desktop/tutorial-sfmlcmake/build
SRCDIR /Users/<me>/Desktop/tutorial-sfmlcmake
CMake Error at build/lib/SFML-2.5.0/SFMLConfig.cmake:139 (message):
  Requested SFML configuration (Static) was not found
Call Stack (most recent call first):
  CMakeLists.txt:38 (find_package)


CMake Error at CMakeLists.txt:38 (find_package):
  Found package configuration file:

    /Users/<me>/Desktop/tutorial-sfmlcmake/build/lib/SFML-2.5.0/SFMLConfig.cmake

  but it set SFML_FOUND to FALSE so package "SFML" is considered to be NOT
  FOUND.
