A generator for conan that can be used to build conan packages by invoking cmake instead of conan build

conancmaketoolchaingenerator's Issues

Simple example

Hi Pepe,

I'm new to Conan and I was checking out your ConanCMakeToolchainGenerator. It looks like something I have been looking for. However, I am not able to set up a simple example.
Using your source, I use the command "conan create . wo/testing.
However, it fails in some way in the testing stage.

• I had to change the arm-none-eabi-gcc_installer package to one built by myself
• It gives the error "CONAN_CMAKE_TOOLCHAIN_FILE was expected but not set." which I can fix through setting the profile "conan create . wo/testing --profile=cross. However, I would also like it to work when not setting a profile. How would I do this?
• Then I get the error "CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set.". I'm not sure why this happens, since the package ninja_installer/1.9.0@bincrafters/stable is included in the build_requires. I don't find the conan docs sufficient on this, so I might be doing something wrong.

It would be very helpful to write down an example, instead of only the CMakeLists file you give now, with for example a project that includes one main file and one dependency. That would really help.

Kind regards.

failing test

When I run
conan create . demo/testing -s compiler=gcc -s compiler.libcxx=libstdc++ -s
compiler.version=5.4

I get:
cmake_toolchain_generator/0.1@demo/testing (test package): ERROR: Generator CmakeToolchain(file:conan_toolchain.cmake) failed
'HelloTestConan' object has no attribute 'install_folder'
ERROR: 'HelloTestConan' object has no attribute 'install_folder'

I'm not sure where this comes from?

[edit]
It seems that CMakeDefinitionsBuilder get_definitions is using the install folder.

Possible replacement

FYI: It looks like conan is starting to support a feature like this natively: https://docs.conan.io/en/1.32/creating_packages/toolchains/cmake.html

Automatically include CONAN_CMAKE_TOOLCHAIN_FILE

This might seem silly, considering this generates toolchain files, but I think it would be helpful for the auto-generated toolchain file to include CONAN_CMAKE_TOOLCHAIN_FILE if the environment variable is provided.

This would allow toolchains providers who need to run additional cmake steps to include them in the CONAN_CMAKE_TOOLCHAIN_FILE, which will then help ensure that building via cmake and building via conan are the same.

In my use case, I would like to add:
set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)
conan-io/conan#4706

PS: thanks for making this toolchain generator is been very helpful
