官网目前的版本要求用VS2019编译windows版本，我也是看了别人流程，之后参考手册折腾了6天，今天终于把release能运行起来了。做个简单的记录，备注如下：
1) 当前版本必须使用VS2019，可以使用免费版本就可以。我开始使用VS2017到了后面的部分报错。
2）我的开发环境是家里的windows10x64，需要注意手册里要求编译各种库为32位，但是特别需要注意的是：cmake和python一定要用x64安装版本，不要使用ZIP包，因为python需要在注册表里添加各种信息，如果注册表里没有，后面cmake在加载依赖时候会报错，并且发现32位版本cmake加载python运行库有问题。经过了2天的折腾，最后换成了cmake-3.16.4-win64-x64.msi和python-3.8.1-amd64.exe解决了telegram生成解决方案时配置的问题。
3）在openssl编译，手册是使用了debug和release分开编译，这个主要是后面的qt5.12要用，按照手册里的方法无法成功配置，总是说无法找到，最后从qt官网找到了5.12.0压缩包编译的。这里简要说明一下：
3.1）openssl
perl Configure no-shared VC-WIN32 no-asm --prefix=D:\TBuild\Libraries\Qt-5.12.5\OpenSSL
nmake install
nmake test
大概意思是编译为静态库，使用32位RELEASE版本，不要汇编（防止以后出现莫名其妙的BUG），安装后放到指定目录，一变后续给QT用。INSTALL后会在 D:\TBuild\Libraries\Qt-5.12.5\OpenSSL出现3个目录：include, lib, bin
3.2）QT
官方给的方法如下：
git clone git://code.qt.io/qt/qt5.git qt_5_12_5
cd qt_5_12_5
perl init-repository --module-subset=qtbase,qtimageformats
git checkout v5.12.5
git submodule update qtbase
git submodule update qtimageformats
cd qtbase
git apply ../../patches/qtbase_5_12_5.diff
cd ..
configure -prefix "%LibrariesPath%\Qt-5.12.5" -debug-and-release -force-debug-info -opensource -confirm-license -static -static-runtime -I "%LibrariesPath%\openssl_1_1_1\include" -no-opengl -openssl-linked OPENSSL_LIBS_DEBUG="%LibrariesPath%\openssl_1_1_1\out32.dbg\libssl.lib %LibrariesPath%\openssl_1_1_1\out32.dbg\libcrypto.lib Ws2_32.lib Gdi32.lib Advapi32.lib Crypt32.lib User32.lib" OPENSSL_LIBS_RELEASE="%LibrariesPath%\openssl_1_1_1\out32\libssl.lib %LibrariesPath%\openssl_1_1_1\out32\libcrypto.lib Ws2_32.lib Gdi32.lib Advapi32.lib Crypt32.lib User32.lib" -mp -nomake examples -nomake tests -platform win32-msvc
但是，我觉得这样获得子模块可能不全造成配置失败，当时报错是：ERROR: Feature 'openssl-linked' was enabled, but the pre-condition '!features.securetransport && libs.openssl' failed.
我的方法是去QT官网找一个ZIP，不打补丁，直接编译，使用的命令参数为：
configure -confirm-license -opensource -debug-and-release -static -force-debug-info -nomake examples -nomake tests -openssl-linked -platform win32-msvc OPENSSL_PREFIX="D:\TBuild\Libraries\Qt-5.12.5\OpenSSL" OPENSSL_LIBS="libssl.lib libcrypto.lib Ws2_32.lib Gdi32.lib Advapi32.lib Crypt32.lib User32.lib" -prefix "D:\TBuild\Libraries\Qt-5.12.5"
编译后会在约定目录生成一大推的静态库文件。
之后就准备真正的工作了。
4）tdesktop
api_id: 17349 api_hash: 344583e45741c457fe1862106095a5eb
configure.bat force -D TDESKTOP_API_ID=17349 -D TDESKTOP_API_HASH=344583e45741c457fe1862106095a5eb -D DESKTOP_APP_USE_PACKAGED=OFF
我使用了测试版本的ID号，没有申请自己的。当时因为CMAKE兼容性问题，一直报告：找到PYTHON可执行程序。其实cmake的support.cmake是默认先去找注册表，然后通过提示在去找根目录参数，所以要保证注册表里有信息。如果再出错，那就是兼容性问题。

如果配置成功了，能看到Telegram.sln，那么和成功就不远了，
我的编译并不顺利，首先是报告缺文件，这主要是因为某些模块的头文件是编译时候自动生成的，要求有顺序。
另外，错误提示：error C2220: 警告被视为错误 ：原因是该文件的代码页为英文，而我们系统中的代码页为中文。
我们需要把警告忽视掉。
