# Development: Export the recipe, build a package and test it (with customconan.cmake)
conan create ./conan 0.0.0@user/testing
conan remove myrepository/0.0.0@user/testing -f

# Development: Export the recipe, build a package and test it (with default conanbuildinfo.cmake)
conan create ./conan 0.0.0@user/testing -tf test_package_default
# Note: recipe is removed later, it is used by a subsequent step

# Command-line usage
conan install myrepository/0.0.0@user/testing
conan install --build myrepository myrepository/0.0.0@user/testing # Should trigger rebuild

# Removal of the recipe
conan remove myrepository/0.0.0@user/testing -f
