Handling dependencies of gtkmm4

[cross-dev-cpp]

Hello,

after a few days fiddling with gtkmm & its dependency cairomm, i have to verify the correctness of the files vcpkg provided.

My setup is Visual Studio v18.9.1 with the latest vcpkg in classic mode, the vs-extension is deinstalled.

gtkmm was installed by vcpkg install gtkmm:x64-windows and it finished successfully.

My cmake-file is this:

cmake_minimum_required(VERSION 4.2)
set(ProjectName "gtkmm-test")
project(${ProjectName} LANGUAGES CXX)
set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_executable(${ProjectName})

find_package(PkgConfig REQUIRED)
pkg_check_modules(GTKMM REQUIRED IMPORTED_TARGET gtkmm-4.0)
target_link_libraries(${ProjectName} PRIVATE PkgConfig::GTKMM)

target_sources(${ProjectName} PRIVATE
cpp/main.cpp
cpp/CApp.cpp)

With that cmake-file Visual Studio obstinately gives me the following error:

CMake Error in G:\Work\VisualStudio\projects\gtkmm-test\CMakeLists.txt:
[CMake] Imported target "PkgConfig::GTKMM" includes non-existent path
[CMake]
[CMake] "E:/git/vcpkg/installed/x64-windows/include/cairomm-1.16"
[CMake]
[CMake] in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:
[CMake]
[CMake] * The path was deleted, renamed, or moved to another location.
[CMake]
[CMake] * An install or uninstall procedure did not complete successfully.
[CMake]
[CMake] * The installation package was faulty and references files it does not
[CMake] provide.

The path listed there really is not existent, i think the right path should be:
E:\git\vcpkg\installed\x64-windows\include\cairomm

This path without version is findable on my machine.

Already tried some fixes with no success, like that:
target_include_directories()
find_path()

The only thread about a similar thing i found is this: 19328 wich is 5 years old and didnt led me to a solution.

Now my guess is, there is an error in the pkgconf-file for cairomm.

So please, can anybody who knows more about it, check that?

Checked the paths with pkgconf and its seems to me there are 2 wrong paths:

pkgconf --cflags cairomm-1.16

-IE:/git/vcpkg/installed/x64-windows/include/cairomm-1.16			<- not existing
-IE:/git/vcpkg/installed/x64-windows/lib/cairomm-1.16/include		<- not existing
-IE:/git/vcpkg/installed/x64-windows/include
-IE:/git/vcpkg/installed/x64-windows/include/cairo
-IE:/git/vcpkg/installed/x64-windows/include/libpng16
-IE:/git/vcpkg/installed/x64-windows/include/pixman-1

pkgconf --cflags cairomm-1.16

The vcpkg port is at 1.19.1. I see a patch for include path. The git history points at #29518, i.e. 1.16.2#2 should carry the fix. Merged more than 3 years ago.

Just learned much about the usage of cmake and i can say the cairomm-pkgconf has no error. Now i use

pkg_check_modules(MyDeps REQUIRED IMPORTED_TARGET gtkmm-4.0 cairomm-1.16 glibmm-2.68)

to find the components. This works for gtkmm and cairomm but wont work for glibmm.

My actual error is:

fatal error C1083: "E:\git\vcpkg\installed\x64 - windows\debug\lib\glibmm - 2.68\include\glibmmconfig.h": No such file or directory

Wondering why the error-message says x64 - windows and glibmm - 2.68 while the real directories are named x64-windows and glibmm-2.68 ?? The glibmmconfig.h is at this path but the real directories have no spaces in their names.

Is it really needed to give cmake the "Dependencies of the dependencies" or is there another way??
