在使用Cygwin编译GDAL时遇到'json.h'文件未找到的错误，而使用VS2017则没有此问题。错误源于编译命令中的路径包含了'/cygdrive/e'，导致找不到头文件。通过修改GDALmake.opt，将GDAL_ROOT的路径改为不包含'/cygdrive/e'的形式，如'e:/osg-osgearth-source/other_3rdParty/gdal-2.3.2'，可以解决这个问题。

用cygwin编译gdal遇到的，用vs2017编译就没有该问题。

对比发现，在cygwin中缺少包含的头文件-I../frmts/zlib -I../ogr/ogrsf_frmts/geojson/libjson，其实不是这个原因，是下面语句中路径里包含了/cygdrive/e，比如-I/cygdrive/e/osg-osgearth-source/other_3rdParty/gdal-2.3.2/alg -I/cygdrive/e/osg-osgearth-source/other_3rdParty/gdal-2.3.2/ogr -I/cygdrive/e/osg-osgearth-source/other_3rdParty/gdal-2.3.2/ogr/ogrsf_frmts -I/cygdrive/e/osg-osgearth-source/other_3rdParty/gdal-2.3.2/gnm -I/cygdrive/e/osg-osgearth-source/other_3rdParty/gdal-2.3.2/apps等。
