I have this code and it works fine to fetch a boost archive and apply needed patches. I also builds fine with my cmake workflow preset.
# ---- Add Boost source tar archive via FetchContent ----
include(FetchContent)
set(BOOST_PATCH_DIR "${CMAKE_CURRENT_SOURCE_DIR}/patches/${BOOST_VERSION}")
set(BOOST_PATCHES "${BOOST_PATCH_DIR}/TheBigBoost.patch")
FetchContent_Declare(
Boost
URL ${BOOST_URL}
URL_HASH SHA256=${BOOST_URL_SHA256}
DOWNLOAD_EXTRACT_TIMESTAMP ON
PATCH_COMMAND git apply -p0 ${BOOST_PATCHES}
SYSTEM
${EXCLUDE_FROM_ALL}
)
FetchContent_MakeAvailable(Boost)
set(BOOST_SOURCE ${Boost_SOURCE_DIR})
message(STATUS "Boost_SOURCE_DIR=${Boost_SOURCE_DIR}")
# TODO(CK): should be a function instead use of BOOST_SOURCE and BOOST_VERSION
include(cmake/CheckBoostVersion.cmake)
message(STATUS "Boost found: ${BOOST_VERSION} ${BOOST_SOURCE}")
# ...
But if I run cmake -L . in binary directory, or if I touch my CMakeLists.txt and run ninja, this happens:
root@06bf603b8cf4:/src/build/Release# cmake -L .
