# Fix for error:
# static library deps/libproj/libproj.gyp:libproj#target has several files with the same basename:
#   geocent: proj/src/geocent.cpp proj/src/conversions/geocent.cpp
#   utils: proj/src/utils.cpp proj/src/apps/utils.cpp
#   internal: proj/src/internal.cpp proj/src/iso19111/internal.cpp
# libtool on Mac cannot handle that. Use --no-duplicate-basename-check to disable this validation.
