Question

我试图用Quarts构建osgEarth。官方网站上的说明如下：

将QT_QMAKE_EXECUTABLE CMake变量指向您想要的qmake.exe 使用和CMake将填充所有其他QT变量。

好。我做了以下事情：

cmake -D QT_QMAKE_EXECUTABLE=/Users/garbart/Qt/5.10.0/clang_64/bin/qmake CMakeLists.txt 
make

并收到以下错误：

Answer 1

这就是我构建OSG，osgQt和osgEarth的方式。

获取OSG，进行配置和构建：

git clone --branch OpenSceneGraph-3.6.2 https://github.com/openscenegraph/OpenSceneGraph.git

mkdir osg-build
cd osg-build
cmake ../OpenSceneGraph
make
sudo make install

获取osgQt，进行配置和构建：

git clone https://github.com/openscenegraph/osgQt.git
mkdir osgqt-build
cd osgqt-build
cmake ../osgQt -DCMAKE_PREFIX_PATH=/opt/Qt/5.6.3/gcc_64/lib/cmake
make
sudo make install

由于osgQt跟不上OSG，所以最后一步可能无法建立。

您将需要编辑CMakeLists.txt并设置用于查找Qt和OSG的目录路径。 CMakeLists.txt还硬引用了特定版本的OSG，这需要进行修改。关于这些问题的清单上已经进行了很多讨论，因此在您阅读本文时可能已经对此进行了分类。

git clone https://github.com/gwaldron/osgearth.git
mkdir osgearth-build
cd osgearth-build
cmake ../osgearth -DCMAKE_PREFIX_PATH=/opt/Qt/5.6.3/gcc_64/lib/cmake

使用ccmake .通过以下设置配置构建：

OSGEARTH_QT_BUILD                ON  
OSGEARTH_QT_BUILD_LEGACY_WIDGE   ON

构建并安装：

make
sudo make install

注意：Qt 5.11也应该起作用。

为什么osgEarth没有用Qt构建？
