Building With CMake and installed GLFW binaries

[thomastjeffery]

This page says that you can add the line

find_package(glfw3 3.2 REQUIRED)

to your CMakeLists.txt, and be able to build the project using CMake.

It does nothing to explain where to put the glfw3 binaries, and does not provide a Findglfw3.cmake, glfw3Config.cmake, or a glfw3-config.cmake file, which CMake needs to evaluate the find_package macro. The precompiled binaries from here do not provide them either.

Simply adding the above find_package line to a simple CMakeLists.txt

cmake_minimum_required(VERSION 2.6)
project(Test)
add_executable(test main.cc)

find_package(glfw3 3.2 REQUIRED)

yields this error:

CMake Error at CMakeLists.txt:6 (find_package):
  By not providing "Findglfw3.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "glfw3", but
  CMake did not find one.

  Could not find a package configuration file provided by "glfw3" (requested
  version 3.2) with any of the following names:

    glfw3Config.cmake
    glfw3-config.cmake

  Add the installation prefix of "glfw3" to CMAKE_PREFIX_PATH or set
  "glfw3_DIR" to a directory containing one of the above files.  If "glfw3"
  provides a separate development package or SDK, be sure it has been
  installed.

Is there an example Findglfw3.cmake, glfw3Config.cmake, or glfw3-config.cmake file somewhere?

@thomastjeffery related glfw/glfw#634

[thomastjeffery]

As far as I can tell, the binary release contains no .cmake files whatsoever.

It really isn't trivial to find a FindGLFW3.cmake file that you can be certain (as a new user) is compatible. If the main docs continue to recommend using CMake, they should really provide this file in releases.

I have this exact same problem. Thanks for raising the issue up!

[varungoel1988]

same issue.. anyone can help??

[jollescott]

Ran into this issue today, solved by installing the libglfw3-dev package instead of libglfw3 on Ubuntu 18.04 LTS. Not sure if it is an optimal solution though.

For reference, I have seen two cases where this happens (these don't seem to be the case for the original user, but will hopefully help others):

1. The case that @jollescott mentions
2. People putting the find_package call before a project declaration

Stumbled upon this via google, adding a "redirect" link.

As explained in glfw/glfw#483 (comment) , when you build and install GLFW then the file glfw3Config.cmake can be found in <install_dir>/lib/cmake/glfw/ .

The file is not available in the precompiled Windows binary release.

Still having this issue using the latest precompiled Windows binaries, can't find any information about where to find these files/where they need to be

Updates on Findglfw3.cmake /glfw3Config.cmake [?] So glfw3 lib binaries, /include but no cmake files for dependent builds. Like Ospay_studio...snipped below....

• for anyone wondering about this issue on Windows with VCPKG, install libigl[glfw], it should pull in the required cmakes.

[weisterki]

glfw3-config.cmake

I installed libigl[glfw], and find the glfw3Config.cmake at C:\src\vcpkg\installed\x86-windows\share\glfw3; but there is no glfw3-config.cmake in any folder.

Same issue, there is a solution?
