依赖库
与cmke的find_package斗志斗勇

我习惯把第三方库分为include、lib、和bin
把 find_package 变成变量、include_directories

# find_package(OpenSceneGraph REQUIRED COMPONENTS osgManipulator osgShadow osgSim osgViewer osgGA osgUtil osgText osgDB osg OpenThreads)set(OPENSCENEGRAPH_ROOT "${PROJECT_SOURCE_DIR}/src/third_party/OpenSceneGraph")
include_directories("${OPENSCENEGRAPH_ROOT}/include")
set(OPENSCENEGRAPH_LIBRARIES"${OPENSCENEGRAPH_ROOT}/lib/libosg.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgDB.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgUtil.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgGA.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgText.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgSim.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgShadow.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgManipulator.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libOpenThreads.dll.a""${OPENSCENEGRAPH_ROOT}/lib/libosgViewer.dll.a")# 从头文件解析 OSG 版本
if(EXISTS "${OPENSCENEGRAPH_INCLUDE_DIR}/osg/Version")file(READ "${OPENSCENEGRAPH_INCLUDE_DIR}/osg/Version" _osg_version)string(REGEX MATCH "OSG_VERSION_MAJOR ([0-9]+)" _ ${_osg_version})set(_osg_major ${CMAKE_MATCH_1})string(REGEX MATCH "OSG_VERSION_MINOR ([0-9]+)" _ ${_osg_version})set(_osg_minor ${CMAKE_MATCH_1})set(OPENSCENEGRAPH_VERSION "${_osg_major}.${_osg_minor}.0")
else()set(OPENSCENEGRAPH_VERSION "3.6.5") # 默认版本号，根据实际情况修改
endif()message(STATUS "Using prebuilt OpenSceneGraph from ${OPENSCENEGRAPH_ROOT}")
message(STATUS "Found OSG version ${OPENSCENEGRAPH_VERSION}")

osgEarth下面的CMakeList.txt

set(SQLite3_FOUND TRUE)
# 可选库：GEOS

set(GEOS_LIBRARIES "${THIRD_PARTY_ROOT}/geos/lib/libgeos_c.dll.a")
link_directories("${THIRD_PARTY_ROOT}/geos/lib/")
set(GEOS_FOUND TRUE)
#PROJ
include_directories("${THIRD_PARTY_ROOT}/proj/include")
set(GDAL_LIBRARIES "${THIRD_PARTY_ROOT}/proj/lib/libproj.dll.a")
link_directories("${THIRD_PARTY_ROOT}/proj/lib/")

lerc需要重新配置，命名空间Lerc-> LercNS

include_directories(BEFORE ../../third_party/lerc/include )
include_directories(BEFORE ../../third_party/lerc )add_osgearth_plugin(TARGET osgdb_lercSOURCESReaderWriterLERC.cpp../../third_party/lerc/src/LercLib/BitMask.cpp../../third_party/lerc/src/LercLib/BitStuffer2.cpp../../third_party/lerc/src/LercLib/Huffman.cpp../../third_party/lerc/src/LercLib/Lerc.cpp../../third_party/lerc/src/LercLib/Lerc_c_api_impl.cpp../../third_party/lerc/src/LercLib/Lerc2.cpp../../third_party/lerc/src/LercLib/RLE.cpp../../third_party/lerc/src/LercLib/Lerc1Decode/BitStuffer.cpp../../third_party/lerc/src/LercLib/Lerc1Decode/CntZImage.cpp../../third_party/lerc/src/LercLib/fpl_Lerc2Ext.cpp../../third_party/lerc/src/LercLib/fpl_UnitTypes.cpp../../third_party/lerc/src/LercLib/fpl_Predictor.cpp../../third_party/lerc/src/LercLib/fpl_Compression.cpp../../third_party/lerc/src/LercLib/fpl_EsriHuffman.cpp)

依赖库主要是GDAL难

#gdal_target_link_libraries(alg PRIVATE PROJ::proj)
target_link_libraries(alg PRIVATE D:/gdal/third_party/proj/lib/libproj.dll.a)

FindPROJ.cmake开头添加

set(PROJ_INCLUDE_DIR "${CMAKE_SOURCE_DIR}/third_party/proj/include")
set(PROJ_LIBRARY "${CMAKE_SOURCE_DIR}/third_party/proj/lib/libproj.dll.a")
include_directories(${PROJ_INCLUDE_DIR})
link_directories(${PROJ_LIBRARY})

4.运行结果
osgearth_map.exe
