[question] CMAKE cannot find libraries added to cmakelists, except for zlib #16080

Closed davidelahoz closed 7 months ago

davidelahoz commented 7 months ago

What is your question?

I'm using conan for managing libraries in a C++ project. When building the example provided in the documentation (https://docs.conan.io/2/tutorial/consuming_packages/build_simple_cmake_project.html), zlib is found and compilation is succesful. However, cmake fails to fine any other library installed with conan 2.

Is there a way to indicate cmake in which folder those libraries can be found? (for example using add_subdirectory)

As an example, I provide conanfile.txt and CMakeLists.txt used for adding opencv to the project, but other libraries like miniz also fail to be found.

conanfile.txt

CMake Error at CMakeLists.txt:14 (find_package):
  By not providing "FindOPENCV.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OPENCV", but
  CMake did not find one.

  Could not find a package configuration file provided by "OPENCV" with any
  of the following names:

    OPENCVConfig.cmake
    opencv-config.cmake

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

Have you read the CONTRIBUTING guide?

Hi @davidelahoz

Thanks for your question.

I would be missing some data:

It is possible that your spelling of OpenCV is wrong, it should be find_package(OpenCV). That spelling should be in the conan install output.

davidelahoz commented 7 months ago

Thanks for answering so fast. Using find_package(OpenCV REQUIRED) and target_link_libraries(example PRIVATE Python::Module opencv::opencv) results in the same error:

Thanks for the feedback.

I'd say the problem is that the toolchain is not being passed:

loading initial cache file /tmp/tmp4h2_fer5/build/CMakeInit.txt
-- The C compiler identification is GNU 11.4.0
-- The CXX compiler identification is GNU 11.4.0

Here, you should typically see a message that the toolchain is passed.

You have hints how to execute it in the output too, at the end:

conanfile.txt: If your CMake version is not compatible with CMakePresets (<3.23) call cmake like: 'cmake <path> -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=/config/workspace/lib/build/Release/generators/conan_toolchain.cmake -DCMAKE_POLICY_DEFAULT_CMP0091=NEW -DCMAKE_BUILD_TYPE=Release'
con

Depending if you can/want to use presets (works great, very convenient), or need to pass the toolchain directly in case of older CMake versions.

Thanks pointing that out. The problem was that I hadn't configured correctly the pyproject.toml file required for building the wheel. Adding the following section solved it:

[tool.scikit-build]
sdist.cmake = true
cmake.version = ">=3.23"
cmake.build-type = "Release"
cmake.args = ["--preset conan-release", "-G Ninja"]

cmake.args = ["--preset conan-release", "-G Ninja"]

That makes sense, the conan-release preset includes the conan_toolchain.cmake that contains the paths so the dependencies are found by find_package() calls.

Regarding "-G Ninja" please be aware that in some cases it is necessary to let Conan know at install time about it with -c tools.cmake.cmaketoolchain:generator=Ninja, specially if the layout is defined.

Thanks for the feedback!

Thanks again! I'll add that just in case I get errors in the future due to ninja
