我在标题中提供了所有信息。 我已经交叉编译了 Qt5.15.3，并尝试用它构建 CQtDeployer，而 CQtDeployer 需要 qtwebengine。
最初我不需要 qtwebengine，但正如我所说，我现在需要它来构建 cqtdeployer 我已经安装了此处指定的 QtWebEngine 所需的所有内容：https://wiki.qt.io/Building_Qt_5_from_Git 并执行了以下操作:
cd qt-everywhere-src-5.15.3/qtwebengine
../qtbase/bin/qmake -r .
make
但是构建 QtWebEngineCore 和 QtPdf 失败，尽管安装了
gperfmake[2]: Entering directory '/xch/qt-everywhere-src-5.15.3/qtwebengine/src/core'
QtWebEngineCore module will not be built. Tool gperf is required to build QtWebEngine.
make[2]: Leaving directory '/xch/qt-everywhere-src-5.15.3/qtwebengine/src/core'
cd pdf/ && ( test -e Makefile || /xch/qt-everywhere-src-5.15.3/qtbase/bin/qmake -o Makefile /xch/qt-everywhere-src-5.15.3/qtwebengine/src/pdf/pdf.pro ) && make -f Makefile

QtPdf will not be built. Tool gperf is required to build QtPdf.

我已经在 Debian12 上使用 QtWebEngine 从源代码构建了 Qt 库。对我来说最困难的部分是安装构建 Qt+QtWebEngine 所需的所有基本依赖项。 这是在 Debian 上安装 Qt 依赖项的脚本： #################################################### ###########

################################################## ############ 之后，我取消存档 qt-exerywhere-opensourcesrc-6.2.x.tar.xz 存档：
tar xf qt-everywhere-opensource-src-6.2.9.tar.xz
然后创建./build和./Qt6.2.x目录：
mkdir Qt6.2.x mkdir build && cd ./build And configured cmake:
../qt-everywhere-src-6.2.9/configure -shared -release -c++std c++20
cmake 在构建目录中配置了 Ninja 项目。 然后我开始建造：
cmake --build . --parallel 4
我大约需要7个小时。
然后将构建的Qt库安装到../Qt6.2.x目录：
cmake --install . --prefix ../Qt6.2.9
P.S.：要构建 Qt6.2.4，需要 3.24.0 或更低版本的 cmake。
