CMake Cookbook

How it works

The install target in CMakeLists.txt is an essential component to this recipe:

install(  TARGETS    hello-conda  DESTINATION    bin  )

This target makes sure that the binary is installed in ${CMAKE_INSTALL_PREFIX}/bin. The prefix variable is defined by Conda in the build step of meta.yaml:

build:  number: 0  binary_relocation: true  script:    - cmake -H. -Bbuild_conda -G "${CMAKE_GENERATOR}" -DCMAKE_INSTALL_PREFIX=${PREFIX} # [not win]    - cmake -H. -Bbuild_conda -G "%CMAKE_GENERATOR%" -DCMAKE_INSTALL_PREFIX="%LIBRARY_PREFIX%" # [win]    - cmake --build build_conda --target install

The build step configures the project, sets the install prefix to ${PREFIX} (intrinsic variable set by Conda), builds, and installs the project. The motivation to call ...
