[CMake] cmake finds libxml2 but still says its missing

[Florian Lindner]

Hello,

I try to compile my software like

cmake -DCMAKE_TOOLCHAIN_FILE=../../toolchain.cmake -DBUILD_SHARED_LIBS=off ../..

> cat ../../toolchain.cmake
SET(CMAKE_SYSTEM_NAME Hazelhen)
SET(CMAKE_C_COMPILER       cc)
SET(CMAKE_CXX_COMPILER     CC)
SET(CMAKE_Fortran_COMPILER ftn)

which gives me the error:

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find LibXml2 (missing: LIBXML2_LIBRARIES) (found version "2.9.4")
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake/Modules/FindLibXml2.cmake:69 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:73 (find_package)


I am a bit puzzled, because it says it found libxml 2.9.4, but then again does not set the $LIBXML2_LIBRARIES.

Usage is

find_package(LibXml2 REQlesUIRED)
include_directories(${LIBXML2_INCLUDE_DIR})

and later

target_link_libraries(foobar PUBLIC ${LIBXML2_LIBRARIES})

cmake version 3.5.2

Thanks!
Florian
