Windows7下编译SQLCipher
目的：完成sqlite的加密，使用sqlcipher4.0.1，将windows，android统一
参照该链接https://github.com/sqlitebrowser/sqlitebrowser/wiki/Win64-setup-%E2%80%94-Compiling-SQLCipher，也就是照着做吧
萌新照搬过来，记录操作步骤
环境：
Visual Studio 2017专业版
vs_buildtools.exe
OpenSSL v1.1.1a https://slproweb.com/products/Win32OpenSSL.html 安装路径C：\ dev \ OpenSSL-Win64
ActiveTcl 8.5（不知道有没有用，反正装了一个）
sqlcipher4.0.1源码 https://github.com/sqlcipher/sqlcipher/releases
准备就绪，开始修改值sqlcipher-4.0.1 \ Makefile.msc
参照链接说的灰常清晰，注意不要输错
对照看吧，可能版本不同，该文件显示不一致
下边对照该版本是第269行

!ENDIF
!ENDIF第968行添加下面代码，该路径“C：\ dev \ OpenSSL-Win64”是你安装的路径
# Flags controlling use of the in memory btree implementation

# SQLITE_TEMP_STORE is 0 to force temporary tables to be in a file, 1 to
# default to file, 2 to default to memory, and 3 to force temporary
# tables to always be in memory.

TCC = $(TCC) -DSQLITE_TEMP_STORE=2
RCC = $(RCC) -DSQLITE_TEMP_STORE=2
# Add -DSQLITE_HAS_CODEC to TCC and RCC
TCC = $(TCC) -DSQLITE_HAS_CODEC
RCC = $(RCC) -DSQLITE_HAS_CODEC
# Add OpenSSL include path to TCC and RCC
TCC = $(TCC) -IC:\dev\OpenSSL-Win64\include
RCC = $(RCC) -IC:\dev\OpenSSL-Win64\include第1183行添加如下代码，其中.lib文件是在“C：\ dev \ OpenSSL-Win64 \ lib”下所有尾缀为.lib文件
# Add OpenSSL library path andd library filenames
LTLIBPATHS = $(LTLIBPATHS) /LIBPATH:C:\dev\OpenSSL-Win64\lib /LIBPATH:C:\dev\OpenSSL-Win64\lib\VC
LTLIBS = $(LTLIBS) capi.lib dasync.lib libapps.lib libcrypto.lib libcrypto_static.lib libssl.lib libssl_static.lib libtestutil.lib openssl.lib ossltest.lib padlock.lib uitest.lib
所有程序-VS2017-Visual Studio Tools-随便打开个黑窗口，切换到sqlcipher-4.0.1 \目录下，执行下边命令
nmake /f Makefile.msc
结果如下：
.lib padlock.lib uitest.lib

LINK : 没有找到 sqlcipher.exe 或上一个增量链接没有生成它；正在执行完全链接
生成了sqlcipher.exe
打开sqlcipher.exe时，显示libcrypto-1_1-x64.dll缺失
该在链接https://blog.csdn.net/qq_37887537/article/details/79455814中找到了答案
libcrypto-1_1-x64.dll文件下载，他的链接如果失效了可以试试
链接：https://pan.baidu.com/s/12uh3c6G-vRRBwYYWUJZ35g
提取码：70ja
下载的libcrypto-1_1-x64.dll文件放置C：\ Windows \ System32目录下，即可
