Failing to use leaf with Conan and CMake

[up2datecyborg]

Hi,

I used for a year stx library, and wanted to give boost::leaf a try.
As of writing the latest version of boost in Conan is 1.80.0.
As the conan package boost-leaf (1.81.0) was marked as deprecated recently, I cannot use leaf with Conan and CMake.
It seems CMake component leaf is inexistent.

In my conanfile.txt I have:
[requires] boost/1.80.0

In my CMakeLists.txt:
find_package(Boost REQUIRED COMPONENTS leaf)

It's failing with:
Conan: Component 'leaf' NOT found in package 'Boost'

Looking at the files in ~/.conan/, the library is there, but there is no reference to it in the conan/cmake files.

Am I doing something wrong?

I tested this out and you should do the following:

conanfile.txt

[requires]
boost/1.80.0
// other dependencies

[generators]
CMakeToolchain
CMakeDeps
VirtualRunEnv

CMakeLists.txt

Find package using config

find_package(Boost REQUIRED CONFIG)

Link project

target_link_libraries(${PROJECT_NAME} PRIVATE Boost::boost)

Thanks, I'll try it, I guess there is no component because it's a header-only lib.

Yeah I'm not sure why they didn't make it into its own component. From the looks of it, only a few items within the boost library are pulled out to their own component.

Sorry for the delay, what you explained is working fine.
Thanks!
