使用cxxTest做单元测试，出现错误：error LNK2019，有哪位大虾比较熟悉的cxxtest工具的么？

利用cxxTest做unit test，按照网上教程，设置好环境变量：CXXTESTDIR 和 PERL
配置文件是：

TARGET:		"$(OutDir)\runner.cpp"

# Where to look for the tests
TESTS            = ..\tests\*.h

# Where the CxxTest distribution is unpacked
CXXTESTDIR       = ..\..\..\..\ProjTools\CxxTest
# Check CXXTESTDIR
!if !exist($(CXXTESTDIR)\cxxtestgen.pl)
CXXTESTDIR       = ..\..\..\ProjTools\CxxTest
!if !exist($(CXXTESTDIR)\cxxtestgen.pl)
CXXTESTDIR       = ..\..\ProjTools\CxxTest
!elseif !exist($(CXXTESTDIR)\cxxtestgen.pl)
!error You must define CXXTESTDIR
!endif   
!endif

# cxxtestgen needs Perl or Python
!if defined(PERL)
CXXTESTGEN       = $(PERL) "$(CXXTESTDIR)/cxxtestgen.pl"
!elseif defined(PYTHON)
CXXTESTGEN       = $(PYTHON) "$(CXXTESTDIR)/cxxtestgen.py"
!else
!error You must define PERL or PYTHON
!endif

# Select the Print formatter, if not already defined
!if !defined(PRINTER)
!if defined(CI_BUILD)
PRINTER = XmlPrinter
!else
PRINTER = PrintfPrinter
!endif
!endif

# The arguments to pass to cxxtestgen
CXXTESTGEN_FLAGS =          \
	--runner=$(PRINTER) \
	--no-eh             \
	--no-static-init    \
	--include=Platform.h
	
# How to generate the test runner, `runner.cpp'
"$(OutDir)\runner.cpp": $(TESTS)
	$(CXXTESTGEN) $(CXXTESTGEN_FLAGS) $(TESTS) >"$(OutDir)\runner.cpp"

已经安装好Perl编译器，频繁出现error LNK2019的错误，并且runner.cpp文件内容是空的，错误如下：
