我已经使用以下命令用vcpkg安装了osgearth软件包：
vcpkg.exe install osgearth:x64-windows
现在我要使用CMake。
cmake_minimum_required (VERSION 3.10.0)
project (osgmap)
add_definitions (-DOSGMAP_EXPORTS)
include_directories (${CMAKE_CURRENT_SOURCE_DIR}/..)
find_package (Osg REQUIRED)
find_package(OsgEarth REQUIRED)
set (PROJECT_SRC
Dummy.cpp
)
add_library (${PROJECT_NAME} SHARED ${PROJECT_SRC})
target_link_libraries (${PROJECT_NAME} mapapi)
target_compile_features (${PROJECT_NAME} PUBLIC cxx_std_17)
问题是我找不到osgearth软件包。我尝试了其他选择。
如何在CMake项目中使用随vcpkg一起安装的OsgEarth？
答案 0 :(得分：0)
简短的答案是，在cmake发行版中有findosg *模块，并且没有任何osgEarth模块可以自动查找程序包路径。包是同时位于库和包含库中的配置或模块定义。 Vcpkg似乎无法自动执行软件包定义，它依赖于CMake安装的模块。可以使用find_library和find_path来定位osgearth文件。
find_library(OSGEARTH_LIBRARY osgearth)
假设您运行vcpkg集成，并将-DCMAKE_TOOLCHAIN_FILE与cmake一起使用。可以找到用vcpkg构建的所有库，但不是全部作为软件包。

在正确设置Context之后，您需要提供一个Reducer文件。您可以使用：
CMAKE_TOOLCHAIN_FILE然后将其添加到您的FindOsgEarth.cmake文件夹和# This module defines
# OSGEARTH_LIBRARY
# OSGEARTH_FOUND, if false, do not try to link to osg
# OSGEARTH_INCLUDE_DIRS, where to find the headers
# OSGEARTH_INCLUDE_DIR, where to find the source headers
# to use this module, set variables to point to the osg build
# directory, and source directory, respectively
# OSGEARTHDIR or OSGEARTH_SOURCE_DIR: osg source directory, typically OpenSceneGraph
# OSGEARTH_DIR or OSGEARTH_BUILD_DIR: osg build directory, place in which you've
# built osg via cmake
