macOS build: EVPATH fails

[ax3l]

I am trying to build ADIOS 2.6.0 on macOS 10.15, compatible with SDK 10.9.
CMake:

cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_POSITION_INDEPENDENT_CODE=ON -DADIOS2_BUILD_EXAMPLES=OFF -DADIOS2_BUILD_TESTING=OFF -DADIOS2_USE_BZip2=OFF -DADIOS2_USE_Fortran=OFF -DADIOS2_USE_MPI=OFF -DADIOS2_USE_PNG=OFF -DHDF5_USE_STATIC_LIBRARIES:BOOL=ON -DCMAKE_DISABLE_FIND_PACKAGE_LibFFI=TRUE -DCMAKE_DISABLE_FIND_PACKAGE_BISON=TRUE -DCMAKE_INSTALL_PREFIX=/usr/local ../ADIOS2-2.6.0
-- The C compiler identification is AppleClang 11.0.3.11030032
-- The CXX compiler identification is AppleClang 11.0.3.11030032

I get the following compile error with EVPATH.
