I have found in library Poco under contrib a PocoConfig.cmake which I've copied under /cmake/Modules
I also added in my CMakeLists.txt:
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
Now I run under /Build/cmake ..
And I keep getting:
CMake Error at CMakeLists.txt:41 (find_package):
By not providing "FindPoco.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Poco", but
CMake did not find one.
Could not find a package configuration file provided by "Poco" with any of
the following names:
PocoConfig.cmake
poco-config.cmake
Add the installation prefix of "Poco" to CMAKE_PREFIX_PATH or set
"Poco_DIR" to a directory containing one of the above files. If "Poco"
provides a separate development package or SDK, be sure it has been
installed.
Obviously CMake is not finding the module file. What am I doing wrong, how to explicitly point CMake to that module file?
The PocoConfig.cmake doesn't works with find_package (otherwise, it would be named FindPoco.cmake), that's why you're getting this error.
Just include the PocoConfig.cmake in your CMakeLists.txt with:
include(${CMAKE_SOURCE_DIR}/cmake/Modules/PocoConfig.cmake)
I've had similar issues. In my case I was recompiling with an old build folder in place - deleting the folder and recompiling worked.

I am using Qt Creator as IDE and MSVC 2019.
I built and installed the pagmo library from the source. Now I am trying to use it for my project.
Even though the installation seems fine, when I try to load it I get strange errors, telling me that "pagmo" is not found. In particular:
error:
By not providing "FindPagmo.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Pagmo",
but CMake did not find one.
Could not find a package configuration file provided by "Pagmo" with any
of the following names:
PagmoConfig.cmake
pagmo-config.cmake
Add the installation prefix of "Pagmo" to CMAKE_PREFIX_PATH or set
"Pagmo_DIR" to a directory containing one of the above files. If
"Pagmo" provides a separate development package or SDK, be sure it has
been installed.
In my CMakeLists.txt I have set the following command:
find_package(Pagmo REQUIRED)
Now, as far as I know FindPagmo.cmake does not exist, BUT I am giving as input parameter Pagmo_DIR, which contains the file pagmo-config.cmake. I can't understand why CMake is not finding it. I also tried to set CMAKE_MODULE_PATH to the same folder but nothing changed.
Does anybody have suggestions on how to solve this problem?
I am setting pagmo directory as follows:
-DPagmo_DIR = C:\Lib\pagmo\install\debug\lib\cmake\pagmo
in that folder I have the following files:
Findpagmo_IPOPT.cmake;
pagmo_export.cmake;
pagmo_export-debug.cmake;
pagmo-config.cmake;
pagmo-config-version.cmake;
PagmoFindBoost.cmake
I am making a project that has a deps folder with all its dependencies, currently it includes a git clone of SDL2 and SDL2_ttf. I'd like to get this project to work without having to install SDL2 or SDL2_ttf separately using home brew for example. My current approach is doing the follow, however, it seems like SDL2_ttf is failing to find the directory of SDL2, how can I fix it?
CMakelists.txt
cmake_minimum_required(VERSION 3.19)
project(app)
add_executable(app MACOSX_BUNDLE src/main.cpp)
# SDL2
add_subdirectory(deps/SDL2)
add_dependencies(app SDL2)
# SDL2_ttf
add_subdirectory(deps/SDL2_ttf)
add_dependencies(app SDL2_ttf)
Error message

P.S. I tried doing SET(SDL2_DIR deps/SDL2) in my CMakeLists.txt as suggested in the error but that doesn't seem to be working, I get the same error message.
SDL2 does contain SDL2Config.cmake, I'm using the latest master of these repos:

I'm trying to compile a Ruby plugin for KDevelop: https://github.com/KDE/kdev-ruby

By not providing "FindKF5.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "KF5", but
CMake did not find one.
Could not find a package configuration file provided by "KF5" (requested
version 5.15.0) with any of the following names:
KF5Config.cmake
kf5-config.cmake
Add the installation prefix of "KF5" to CMAKE_PREFIX_PATH or set "KF5_DIR"
to a directory containing one of the above files. If "KF5" provides a
separate development package or SDK, be sure it has been installed.
How, on Ubuntu, do I install something that provides KF5Config.cmake? Preferably without rebuilding KDevelop or KDE or Qt5.
KDevelop relies on the development headers for various libraries, and finds them via the accompanying CMake files.
The build also uses CMake modules provided by the extra-cmake-modules package.
You must install that and libkf5config-dev.
The apt-file command might help you find the relevant packages for your distro in these situations.
I am trying to find the required library for my cmake file but i am unable to find it.
This is my cmake code:
find_package(myLib REQUIRED)
This is the error msg which is being shown:
CMake Error at CMakeLists.txt:10 (find_package):

Can i know how to fix this.
Maybe you have not added the folder where you placed the custom FindmyLib.cmake to CMAKE_MODULE_PATH.
For example if you have placed FindmyLib.cmake in the folder cmake/modules relative to the CMakeList.txt you are using, add
set(CMAKE_MODULE_PATH
${CMAKE_MODULE_PATH}
${CMAKE_CURRENT_SOURCE_DIR}/cmake/modules
)
in the CMakeList.txt
I installed Ogre3D 1.8.1 (the source package) on Ubuntu 12.04 and everything went fine (I managed to run some samples on the Ogre interface). However, I hit a problem while I was compiling an external project (that one) that needed the OpenCV, ArUco and Ogre librarys. When I run the CMake of the project, I receive the following:
CMake Error at CMakeLists.txt:46 (find_package):
By not providing "FindOGRE.cmake" in CMAKE_MODULE_PATH this project has

I know where the FindOGRE.cmake is, it's in the /usr/local/lib/OGRE/cmake, but I don't know how to say to CMake to look for that folder and fix this problem.
You just need to use the -D command line option along with the CMAKE_MODULE_PATH variable:
cmake . -DCMAKE_MODULE_PATH=/usr/local/lib/OGRE/cmake
Just for the record, an alternative solution would be to add the module path directly in the CMakeLists.txt. For example (tested on Debian 9):
set(CMAKE_MODULE_PATH "/usr/share/OGRE/cmake/modules/;${CMAKE_MODULE_PATH}")
Just make sure to add the line before find_package is called.
For me, it only works to set the following in CMakeLists.txt before find_package:
set(OGRE_DIR /usr/share/OGRE/build/sdk/CMake)
Note that the CMake directory is the one containing OGREConfig.cmake. For some reason, my CMake ignores CMAKE_MODULE_PATH.
Maybe, of some help for someone
For me, this solution work on manjaro:
set(CMAKE_MODULE_PATH "/usr/lib/OGRE/cmake;${CMAKE_MODULE_PATH}")
find_package(OGRE QUIET)
if (OGRE_FOUND)
include_directories( ${ogre_INCLUDE_DIR})
link_directories(${OGRE_LIBRARIES})
message(STATUS "OGRE: FOUND")
else()
message(STATUS "OGRE: NOT FOUND")
endif()
