This implies that we will not link against the gmsh library. Unfortunately, on first configure pass the variable `GMSH_WITH_API` is still populated with a `TRUE` value and the `DEAL_II_GMSH_WITH_API` variable gets set by accident and final linkage fails. This issue is hard to spot because a second invocation of cmake will cure the configure mistake (and the debian/ubuntu packages do not run any autodetection). --- diff --git a/cmake/configure/configure_50_gmsh.cmake b/cmake/configure/configure_50_gmsh.cmake index 53f93ea485..afb6f19c99 100644 --- a/cmake/configure/configure_50_gmsh.cmake +++ b/cmake/configure/configure_50_gmsh.cmake @@ -17,5 +17,8 @@ # Configuration for the gmsh executable: # +macro(feature_gmsh_configure_external) + set(DEAL_II_GMSH_WITH_API ${GMSH_WITH_API}) +endmacro() + configure_feature(GMSH) -set(DEAL_II_GMSH_WITH_API ${GMSH_WITH_API})
