BUILDING LIBRARIES NOT (YET?) IN MXE
====================================

(not needed if you download my prebuilt mxe-* packages instead!)

# for building netcdf
sudo apt install mxe-x86-64-w64-mingw32.static-curl

# for building getdata
sudo apt install mxe-x86-64-w64-mingw32.static-libltdl

# Get and unpack the getdata-0.10.0 zip for Windows
mkdir build && cd build &&
x86_64-w64-mingw32.static-cmake ../getdata-0.10.0/cmake

# netcdf 4.7.4
mkdir build && cd build &&
x86_64-w64-mingw32.static-cmake ../netcdf-c-4.7.4 -D"BUILD_UTILITIES=OFF" -D"ENABLE_TESTS=OFF"

# netcdf-cxx4 4.3.1 (not needed for kst)
mkdir build && cd build &&
x86_64-w64-mingw32.static-cmake ../netcdf-cxx4-4.3.1
# and xx times add libraries link options missing from linklibs.rsp - something is broken

# netcdf-cxx 4.2 (legacy)
mkdir build-win && cd build-win &&
../netcdf-cxx-4.2/configure --host=x86_64-w64-mingw32.static --prefix=/usr/lib/mxe/usr/x86_64-w64-mingw32.static


BUILDING KST
============

# Generate makefiles and check all plugins are enabled (libraries found)
